Expert Solution & Answer
Check Mark
To determine

The two popular operating voltages for residences.

Answer to Problem 1RQ

The two popular operating voltages for residences are 115V and 230V.

Explanation of Solution

The residences are generally furnished with the single phase power supply.

The below figure represents the wiring diagram of main circuit breaking panel for a residence.

  Refrigeration and Air Conditioning Technology (MindTap Course List), Chapter 17, Problem 1RQ

    Figure-(1)

The voltages 115V (single phase) is used for the common appliances like TV, fan many other and 230V (single phase) is used for the heavy duty appliances like electric oven, dryer, refrigerators and air conditioners.

The equipment which are used in commercial buildings and the factories requires three phase power supply.

The voltage 460V (three phase) is used for the electric motors and 560V (three phase) is used for the industrial systems.

Conclusion:

The two popular operating voltages for residences are 115V and 230V.
